Auditory Pathway Verification Study of Bone Conduction Signal by ABR and MeMRI

The hearing aids transmit voice in the manner of transmitting voice by air conduction method which is the same generation mechanism as ambient noise and various voice signals. The problem is that it is difficult to transmit clear speech in robust environmental noise, and it is difficult to analyze a signal in a signal that is similar to a voice signal, which is a desired transmission signal. Recently, in order to overcome these disadvantages, a method of transmitting voice signals using a bone conduction system having different mechanisms of occurrence has been used. However, the effectiveness of the bone conduction method and the transmission path of the voice signal transmission are not clarified, and thus there is a problem with the verification method of the efficiency. In this paper, to overcome these problems, we verified the signal transmission efficiency of an animal model with bone conduction oscillator using ABR (Auditory Brainstem Response) and MeMRI (Manganese Enhancement MRI).
